Abstract

A reversed-F-shaped antenna is provided with a low frequency radiation arm, a high frequency radiation arm and a main signal line; one end of the high frequency radiation arm is connected with a ground wire; the main signal line stretches out upward from the high frequency radiation arm; and a mono signal point is arranged on the connecting position of the main signal line and the high frequency radiation arm. A loop formed by the connection between the ground wire and the signal point helps the antenna to produce high-frequency effect.

Description

Inverted F shaped antenna

Technical field

The present invention relates to a kind of inverted F shaped antenna, and more specifically say, relate to the inverted F shaped antenna of the reeled reduced volume that a kind of suitable mobile computer uses.

Background technology

Because wireless communication technology and portable electronic device (like mobile computer etc.) progress, with regard to the utilization of antenna, increasingly high to densification and multifrequency performance demands.The antenna that how a kind of excellent in efficiency is provided and is fit to install in the various mobile computers is the target that industry is sought always.

In the disclosure of the Invention communique of Taiwan (TW), openly number 200713705 the name be called " multiple frequency antenna structure " in first to file; A solution is provided, and it mainly has a ground plane, the first radiation metal arm, the first parasitic short circuit metal arm and the second parasitic short circuit metal arm.Utilize the first parasitic short circuit metal arm and the second parasitic short circuit metal arm respectively with the first radiation metal arm coupled resonance, and can form two effect frequency ranges, to form the multifrequency performance.

Because this when being wound into elongated rod shape (I-bar), because of its structural relation must could be fixed by a fixture (holder), so has its shortcoming in combination in the structure of first to file, remain improvement.

Summary of the invention

The present invention provides a kind of inverted F shaped antenna, and this antenna has low frequency radiation arm, high frequency radiation arm and main signal line; This high frequency radiation arm end connects ground wire, and this main signal line extends upward out from the high frequency radiation arm, and the mono signal load point is arranged on main signal line and the high frequency radiation arm link position.By the loop that is connected to form between ground wire to load point (loop), make antenna produce high-frequency effects.

Inverted F shaped antenna provided by the present invention can directly be wound into hollow elongated rod shape (I-bar), perhaps is attached on the soft board and reels, and to dwindle the entire antenna volume, is fit to be assemblied in the various mobile computers.

Below, will introduce execution mode of the present invention in detail with reference to accompanying drawing.

Embodiment

See also Fig. 1 and Fig. 2, inverted F shaped antenna provided by the present invention has low frequency radiation arm 10, high frequency radiation arm 20 and main signal line 30.

Low frequency radiation arm 10 has shape, thereby extends low frequency parasitic 11.And high frequency radiation arm 20 has ground connection end 50, and this ground connection end 50 is used for connecting ground wire.30 of main signal lines extend upward from high frequency radiation arm 20, become branch-like to stretch out, and on main signal line and position that above-mentioned high frequency radiation arm is connected formation mono signal load point 40, thereby be connected with holding wire.

Referring to Fig. 2, thought of the present invention is that 40 of ground wire to load points that utilize ground connection end 50 to connect are connected to form a loop (loop), shown in arrow among the figure, produces high-frequency effects by this loop, makes the antenna can be in the high band effect.

And low frequency radiation arm 10, high frequency radiation arm 20 and main signal line 30 are the flexible metal material, can be folding along the dotted line among Fig. 1, and as shown in Figure 3 to be wound into a hollow elongated rod shape (I-bar), be fit to be assemblied in the various mobile computers.

Low frequency radiation arm 10, high frequency radiation arm 20 and main signal line 30 can be carried on the soft board, and folded roll is around reduced volume.Also can be as shown in Figure 4, the folding hollow elongated rod shape that forms is arranged at insulation stock 60 in appearance.

Referring to (Fig. 5 is another angular views of Fig. 4) shown in Figure 5, low frequency radiation arm 10 is after folding, and low frequency parasitic 11 constitutes capacitive coupled resonance structures with main signal line 30, thereby produces low-frequency effects, makes the antenna can be in low-frequency range work.

Therefore; The present invention's low frequency radiation arm capable of using 10, high frequency radiation arm 20, ground connection end 50 connect 40 loops that are connected to form of ground wire to load point (loop) and low frequency parasitic 11 and main signal line 30 near coupled resonance; And produce a plurality of working frequency range, make antenna reach the multifrequency function.
